We got to the desert late about 3pm and got to ride at about 4:30pm and as the sun went down the temp was about 65 or less and the blue buggy ran great in the sand washes and came out of the corners fast but would rpm out to 8600 fast. It also on take off would spin the tires hard and upshift but not too fast like with the31t and clutch slipage.This was with the 10.5/12.5 rollers and the motorio pulley in the stock mode.
We went on a ride the next morning and it was about 78/82 and windy. We were trying to keep up with my brother in law and kids who were on motorcycles and after about 20/30 minuets of 7200/7600 rpms it blew out the gasket just below the starter. It also would not run good when it got hot.
The red buggy with the 31t was cruising at 6000/6400 rpm about 28/30 mph no problem.
I put the 39t back on thinking that my cruise rpm would be lower and probally should of ran heavier rollers like 12/14. The top speed is better, two trips ago it topped out at 28mph with a dr pulley variator and 10/11 sliders and 39t. Same set up with the 31t ran37mph.
After getting back to camp I cleaned the back of the block and put Honda bond silicone on at let it cure for 4 hours or more and back to riding just kept the rpms below 7000 and it would still get hot and vibrate and had no power above 6000 after it got hot.
I am going back to the 31t and going to jet from a 125 to a 127.5 after removing the motor and replacing the gaskets. Also need to save up for a oil cooler.
The last day of our trip I put the 10/12 sliders in and worked great didn't have any problem with the sliders falling back like with the 10/11 or the all 11 set up like before.
I think the sliders need to be at least 2 grams apart to work properly.
So we had a good trip just should of left the 31t on and kept the rpms down that also caused high crank case pressure.
